Hi all
I created a function that returns a set of records. This function returns an integer and a float as the record fields. I have a problem in this function, it truncates the output. e.g. 1342 is displayed as 134, 456.46 is displayed as 456. In other words, it displays the first 3 digits only of a number, whether it is integer of float. I traced the function and the results are computed correctly. I use PostgreSQL 8.2.4. Following is a piece of my code.
int counter;float result;
//some code
char **output; output = (
char**)palloc(2*sizeof(char*)); //allocate space for two string pointeroutput[0] = (
char*)palloc(sizeof(int)); //allocate space for a string that accepts an integeroutput[1] = (
char*)palloc(sizeof(double)); //allocate space for a string that accepts an integersnprintf(output[0],
sizeof(int), "%d", counter); snprintf(output[1],
sizeof(float), "%.5f", result); HeapTuple data;
Datum finalResult;
data = BuildTupleFromCStrings(attinmeta, output);
finalResult = HeapTupleGetDatum(data);
SRF_RETURN_NEXT(funcctx, finalResult);
---------------
Any idea what could be the cause of this error?
